LIFE-SAVING AND SWIMMING DEVICE.

Application filed May 31, 1924. Serial No. 717,158.

To all "whom it may concern:

Be it known that I, Monnrs ELrnNsoN, a subjeit of the King of Rumania, residing at the city of Toronto, in the Province of Ontario, in the Dominion of Canada, have invented new and useful Improvements in Life-Saving and Swimming Devices, of which the following is a specification.

The invention relates to improvements in life saving and swimming devices as described in the present specification and shown in the accompanying drawings which form part of the same.

The invention consists essentially of a plurality of air chambers intercommunicating through passageways and provided with a valve so disposed that when the device is strapped in position upon the wearer the same lies conveniently situated in proximity to his mouth for purposes of inflating the device.

The objects of the invention are to provide a device of the kind referred to that may be stored or kept ready for use in a deflated condition, that it may be quickly inflated and used as a buoy to be thrown to a party in distress in the water; one which, furthermore, can be used as a swimming device of the water-wings variety; and as a buoy to be carried on board-ship, where, in the event of danger, it could be continu ously worn in its deflated condition by passengers and inflated by them when emergency arose.

Referring to the drawings, Figure 1 is a view of the device deflated. Figure 2 is a view of the device in place upon a person. Like numerals of. reference indicate corresponding parts in each figure throughout the drawings.

In the drawings, the numeral 1 indicates the air chambers, which are preferably circular in shape, and intercommunicating by These chambers are arranged in two' groups, one forming the front of the device and composed of three of such chambers in triangular shaped formation, and the other forming the rear of the device consisting of a pair of such chambers.

Extending from the passageways of the front portion of the device is a comparaof this opening, preferably about the centre-front of this neckpiece.

5 are straps extending from the several chambers 1 for the purpose of fastening the device upon the wearer.

In the use of this invention, the device is fitted upon the person of the wearer by placinghis head through the opening in the web t and allowing the web portion to rest upon his shoulders, the front triangular group of chambers being upon the front of his person, and the pair of chambers upon his back. Fastening is then achieved by connecting the straps 5 and tying.

The device may be worn in this manner in a deflated condition, the valve stem 3 being readily accessible for the purpose of placing in the wearers mount for inflation of the chambers as and when required.

IVhat I claim is In a life saving and swimming device, a group of air chambers in triangular formation for disposition at the front of the wearer, a further group for disposition upon his back; passageways connecting such chambers one with another, a web forming a neck-piece between the two groups, straps for fastening the device upon the wearer, a valve stem for the purpose of extending to the mouth of the wearer, and a valve carried by such stem.
